[0001] This application relates to the field of new energy technology, and more specifically to a battery packing device. Background Technology

[0002] Currently, with the large-scale development of renewable energy (such as wind power and solar power), energy storage equipment has also ushered in a period of rapid development. For example, energy storage boxes are now often used to load energy storage batteries for rapid deployment.

[0003] Due to the diversity of energy storage box products, the inconsistency of battery rack specifications inside the box, the inconsistency of battery specifications and dimensional errors, coupled with the lack of flexibility of the packing equipment, the existing battery packing equipment is inefficient when packing, and may even cause batteries to be bumped or damaged.

[0004] Therefore, a battery packing device is needed to at least partially solve the above problems. Summary of the Invention

[0005] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This summary section is not intended to limit the key and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] To at least partially solve the above problems, this application provides a battery loading device for placing batteries into an energy storage box. The battery loading device includes: a base frame assembly for vertical movement under the action of a lifting device, and a hinge assembly disposed on the base frame assembly; a support frame, which is pivotally connected to the base frame assembly via the hinge assembly, and the hinge axis between the support frame and the base frame assembly extends along a first direction; a loading conveyor assembly disposed on the support frame for conveying batteries along the first direction; and an angle adjustment assembly including an actuation component and a follower component. The actuation component is disposed at the end of the base frame assembly along the first direction, and the follower component is disposed at the end of the support frame along the first direction. The follower component is offset relative to the hinge assembly along a second direction, which is perpendicular to the first direction. The follower component is connected to the actuation component and configured to move up and down under the action of the actuation component.

[0007] According to the battery loading device of this application, by pivoting the support frame and the base frame assembly and setting the angle adjustment component, the base frame assembly can rotate about the battery conveying direction as the axis, thereby realizing the fine-tuning of the battery angle about the conveying direction as the pivot axis when conveying the battery, so that the battery conveying direction can be accurately matched with the position of the battery rack in the energy storage box.

[0008] Optionally, the actuation assembly includes a drive assembly and an actuator, the actuator being connected to the drive assembly and configured to move along the second direction under the action of the drive assembly; the follower assembly includes a track member, the track member having a track groove inclined relative to the vertical, the actuator being housed in the track groove. According to this solution, the linear movement of the actuator can be converted into the up-and-down movement of the track member, thereby driving the support frame to rotate.

[0009] Optionally, the drive assembly includes a servo motor and a lead screw assembly, and the actuator includes an actuation bearing, the inner ring of which is connected to the lead screw assembly, and the outer ring of which contacts the wall of the track groove. According to this solution, the conversion efficiency for linear movement is high.

[0010] Optionally, the hinge assembly includes: two first hinge frames disposed on both sides of the beam along the edge of the base frame assembly in the first direction, the first hinge frames extending vertically and higher than the support frame; and a second hinge frame disposed between the two first hinge frames and connected to the two first hinge frames via a hinge shaft, the bottom surface of the second hinge frame being connected to the upper surface of the support frame. According to this solution, the structure is simplified and the connection strength is high.

[0011] Optionally, the pivotable angle range of the support frame relative to the horizontal plane is ±5°.

[0012] Optionally, the base frame assembly includes: an outer frame for vertical movement under the action of a lifting device; and a bottom frame, on which the actuation assembly is disposed, the support frame being pivotally connected to the bottom frame via the hinge assembly, and the bottom frame being at least partially flexibly suspended below the outer frame. According to the above configuration, the support frame and the bottom frame are flexibly suspended together on the outer frame. This flexible connection allows the battery to be cushioned by its own displacement when the edge is bumped during battery insertion, and to adjust its position for precise alignment, avoiding battery damage caused by impacts from a rigid connection without cushioning.

[0013] Optionally, the outer frame is provided with fork slots, and the outer frame is used to cooperate with a forklift. According to this solution, the structure is simple and efficient.

[0014] Optionally, the outer frame is provided with multiple hangers, and the edge of the bottom frame is provided with multiple connecting parts. The positions of the multiple connecting parts correspond one-to-one with the positions of the multiple hangers, and the connecting parts are at least partially located below the hangers. The connecting parts are connected to the hangers by chains. According to the above configuration, the chain hoisting strength is high and the cushioning is good, and the above structural design has high space utilization.

[0015] Optionally, the outer frame includes an outer frame body constructed as a rectangular frame, the hanger includes columns and hanging plates, the columns extend vertically and are connected to the four corners of the outer frame body, the hanging plates are connected to the top of the columns and extend out of the outer frame body along the first direction; the bottom frame includes a bottom frame body constructed as a rectangular frame, the connecting portions are disposed at the four corners of the bottom frame body and protrude out of the bottom frame body along the second direction, and the connecting portions are located below the hanging plates. According to this solution, flexible hoisting is more stable.

[0016] Optionally, limiting members are also provided at the four corners of the outer frame body. The limiting members protrude from the outer frame body along the first direction and have limiting grooves. A limiting post extending vertically is provided at the bottom of the connecting part. The limiting post extends into the limiting groove and is movable within the limiting groove. According to this solution, the movable range of the bottom frame can be limited, reducing the possibility of accidental battery collisions caused by large-scale shaking of the bottom frame when moving the equipment into the box.

[0017] Optionally, the battery loading device includes two loading conveying assemblies, each comprising: a horizontal moving device having a driving part and a moving part, the moving part being configured to move along a second direction under the action of the driving part; and a conveying device disposed on the moving part, the conveying device being used to carry the battery and convey the battery along the first direction. According to the above configuration, different battery specifications can be adapted by adjusting the position of the conveying device.

[0018] Optionally, the battery loading device includes two sets of propulsion assemblies, which are spaced apart from each other on the support frame along the second direction. Each propulsion assembly includes a drive member and a push rod. The push rod is configured to move along the first direction under the action of the drive member to apply a pushing force to the battery when it is partially transferred out of the loading conveyor assembly. According to this solution, after the battery is partially transferred out of the conveying device, the conveying device can no longer transport the battery. By applying a pushing force to the battery through the propulsion assembly, the battery can be moved entirely out of the battery loading device and into the container.

[0019] Optionally, the support frame is provided with a track assembly extending along the first direction, the propulsion assembly further includes a traveling device, the drive member is disposed in the traveling device and configured to drive the traveling device to move along the track assembly, and the push rod is disposed in the traveling device.

[0020] Optionally, the push rod is pivotally connected to the traveling device and configured to pivot along a horizontal plane; the propulsion assembly further includes an elastic element connected between the traveling device and the push rod and configured to apply an elastic force to the push rod, wherein the elastic force drives the two push rods to pivot in a direction of approaching each other; the support frame is also provided with a blocking wheel assembly, and a blocking bar is provided at the end of the push rod, the blocking bar protruding from the side of the push rod in the direction of approaching each other, when the traveling device moves backward to a predetermined position, the blocking bar interferes with the blocking wheel assembly, so that the two push rods pivot in a direction of moving away from each other. According to this solution, when the propulsion assembly retracts to a designated position, the push rods can automatically open to each other, thus not obstructing the placement of the battery on the conveying device, and when it is necessary to apply a pushing force to the battery, the push rods can automatically close behind the battery.

[0026] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings.

[0027] Referring to Figures 1 and 2, this application provides a battery loading device 100 for placing batteries into an energy storage box. The battery loading device 100 includes a base frame assembly, a support frame 130, a loading conveying assembly 140, and an angle adjustment assembly 150. The base frame assembly is used to move vertically under the action of a lifting device, and a hinge assembly 160 is provided on the base frame assembly. The support frame 130 is pivotally connected to the base frame assembly via the hinge assembly 160, and the hinge axis 163 between the support frame 130 and the base frame assembly extends along a first direction D1. The loading conveying assembly 140 is disposed on the support frame 130 and is used to convey batteries along the first direction D1. The angle adjustment assembly 150 includes an actuation assembly 151 and a follower assembly 155. The actuation assembly 151 is disposed at the end of the base frame assembly along the first direction D1, and the follower assembly 155 is disposed at the end of the support frame 130 along the first direction D1. The follower assembly 155 is offset relative to the hinge assembly 160 along a second direction D2, which is perpendicular to the first direction D1. The follower assembly 155 is connected to the actuation assembly 151 and configured to move up and down under the action of the actuation assembly 151. Preferably, the pivotable angle range of the support frame 130 relative to the horizontal plane is ±5°. More preferably, the pivotable angle range of the support frame 130 relative to the horizontal plane is ±3°.

[0028] According to the battery loading device 100 of this application, the base frame assembly can be rotated about the battery conveying direction by pivoting the support frame 130 with the base frame assembly and setting the angle adjustment assembly 150. This enables the battery to be finely adjusted about the angle of rotation about the conveying direction when the battery is being transported, so that the battery conveying direction can be accurately matched with the position of the battery rack in the energy storage box.

[0029] The specific structure of the angle adjustment component 150 can be seen in Figures 2, 3, and 4. The actuation component 151 includes a drive component 152 and an actuator 153. The actuator 153 is connected to the drive component 152 and is configured to move along the second direction D2 under the action of the drive component 152. The follower component 155 includes a track member 156, on which a track groove 157 inclined relative to the vertical is formed. The actuator 153 is housed in the track groove 157. Therefore, when the actuator 153 moves linearly along the second direction D2 under the drive of the drive component 152, it interferes with the track member 156, causing the track member 156 to move up and down, thereby rotating the support frame 130.

[0030] The drive assembly 152 may include a cylinder assembly or a lead screw assembly. For example, the drive assembly 152 includes a servo motor and a lead screw assembly, and the actuator 153 includes an actuation bearing. The inner ring of the actuation bearing is connected to the lead screw assembly, and the outer ring of the actuation bearing is in contact with the wall of the track groove 157.

[0031] Taking the initial state shown in Figure 4 as an example, when the drive assembly 152 includes a servo motor and a lead screw assembly, the drive assembly 152 drives the nut of the lead screw assembly to move to the left along the second direction D2, and the actuator 153 follows suit and moves to the left. Due to the restriction of the track groove 157, the actuator 153 causes the track member 156 to move upward, thereby lifting the left end of the support frame 130 in the figure and achieving a clockwise deflection of a certain angle. When the drive assembly 152 drives the nut of the lead screw assembly to move to the right along the second direction D2, the actuator 153 follows suit and moves to the right. Due to the restriction of the track groove 157, the actuator 153 causes the track member 156 to move downward, thereby lowering the left end of the support frame 130 in the figure and achieving a counterclockwise deflection of a certain angle.

[0032] The hinge assembly 160 includes two first hinge frames 161 and a second hinge frame 162. The two first hinge frames 161 are disposed on both sides of the beam at the edge of the base frame assembly along the first direction D1, extending vertically and higher than the support frame 130. The second hinge frame 162 is disposed between the two first hinge frames 161 and connected to them via a hinge shaft 163, with the bottom surface of the second hinge frame 162 connected to the upper surface of the support frame 130. The battery charging device 100 preferably has two sets of hinge assemblies 160, located on opposite sides of the base frame assembly along the first direction D1, with the hinge shafts 163 of the two sets of hinge assemblies collinear. More preferably, the hinge assembly 160 is disposed at the midpoint of the rack assembly along the second direction D2. Correspondingly, the battery loading device 100 preferably has two sets of angle adjustment components 150, which are located on both sides of the base frame assembly along the first direction D1.

[0033] Referring to Figures 1, 2, and 5, the base frame assembly includes an outer frame 110 and a bottom frame 120. The outer frame 110 is used for vertical movement under the action of a lifting device. As an example, the outer frame 110 is provided with a fork slot 112, and the outer frame 110 is used to cooperate with a forklift, so that the outer frame 110 can be raised and lowered under the action of the forklift. The bottom frame 120 is at least partially flexibly suspended below the outer frame 110. The aforementioned support frame 130 is pivotally connected to the bottom frame 120 via a hinge assembly 160, and an actuation assembly 151 is disposed on the bottom frame 120. Thus, the support frame 130 and the bottom frame 120 are flexibly suspended together on the outer frame 110. The flexible connection allows the battery to be cushioned by its own displacement when the edge is bumped during battery insertion, and to adjust its position to achieve precise alignment, avoiding battery damage caused by impacts without cushioning in a rigid connection.

[0034] More specifically, the outer frame 110 includes an outer frame body 111 constructed as a rectangular frame and a plurality of hangers 113, which are disposed on the outer frame body 111. The hangers 113 include columns 114 and hanging plates 115. The columns 114 extend vertically and are connected to the four corners of the outer frame body 111, and the hanging plates 115 are connected to the top of the columns 114 and extend out of the outer frame body 111 along a first direction D1.

[0035] The base frame 120 includes a rectangular base frame body 121 and multiple connecting portions 123. The connecting portions 123 are located at the four corners of the base frame body 121 and protrude from the base frame body 121 along a second direction D2. The multiple connecting portions 123 correspond one-to-one with the positions of multiple hangers 113, and the connecting portions 123 are located below the hanging plates 115. The connecting portions 123 are connected to the hanging plates 115 of the hangers 113 by chains 122.

[0036] As one implementation, limiting members 116 are also provided at the four corners of the outer frame body 111. The limiting members 116 protrude from the outer frame body 111 along the first direction D1 and have limiting grooves 117. A limiting post 124 extending vertically is provided at the bottom of the connecting part 123. The limiting post 124 extends into the limiting groove 117 and can move within the limiting groove 117. This limits the range of motion of the bottom frame 120 and reduces the possibility of accidental battery collisions caused by large-scale shaking of the bottom frame 120 when moving the device into the box.

[0037] Referring to Figures 1 and 2, the battery loading device 100 includes two loading conveying assemblies 140, each comprising a horizontal moving device 141 and a conveying device 144. The horizontal moving device 141 has a drive unit 142 and a moving unit 143, the moving unit 143 being configured to move along a second direction D2 under the action of the drive unit 142. The conveying device 144 is disposed on the moving unit 143 and is used to carry the battery and convey it along a first direction D1. The conveying device 144 is preferably a chain conveyor. Thus, the position of the conveying device 144 can be adjusted by the horizontal moving device 141 to accommodate batteries of different sizes. Furthermore, the conveying device 144 may also be provided with a guide structure, the sides of which have multiple rollers. Two sets of rollers in the guide structure face each other, so that during battery conveying, the two sets of guide structures clamp the battery in the middle, restricting the forward conveying of the battery between the two sets of guide structures.

[0038] In one implementation, the horizontal moving device 141 can be constructed as a lead screw assembly, for example, a drive unit 142 can drive the lead screw to rotate, and a moving part 143 is threadedly engaged with the lead screw to move along the lead screw. In the embodiment shown in FIG1, the moving part 143 is shown in a state where it is not assembled with the conveying device 144. A fixing member 145 is provided on the side of the conveying device 144, which can be fixedly connected to the moving part 143, for example, by bolt fastening.

[0039] The support frame 130 is also provided with a horizontal rail 132 extending along the second direction D2, and a movable member 133 is provided on the horizontal rail 132, which can move along the horizontal rail 132. The bottom of the conveying device 144 is provided with a limiting structure 146, which is connected to the movable member 133, so that the conveying device 144 can be easily moved by the horizontal moving device 141.

[0040] Referring to Figures 1 and 6, the battery loading device 100 includes two sets of propulsion assemblies 170, which are spaced apart along a second direction D2 on the support frame 130. Each propulsion assembly 170 includes a drive member 171 and a push rod member 172. The push rod member 172 is configured to move along a first direction D1 under the action of the drive member 171, applying a pushing force to the battery when it is partially transferred out of the loading and unloading conveying assembly 140. After the battery is partially transferred out of the conveying device 144, slippage occurs between the conveying device 144 and the battery, rendering it unable to convey the battery further. This design, however, uses the propulsion assemblies 170 to apply a pushing force to the battery, allowing the battery to be completely removed from the battery loading device 100 and placed into the container.

[0041] The support frame 130 is provided with a track assembly 131 extending along the first direction D1. The propulsion assembly 170 also includes a traveling device 173. The drive member 171 is disposed in the traveling device 173 and configured to drive the traveling device 173 to move along the track assembly 131. The push rod member 172 is disposed in the traveling device 173. As an example, the traveling device 173 and the track assembly 131 can be in a gear and rack engagement.

[0042] More specifically, push rod 172 is pivotally connected to the traveling device 173 and configured to pivot along a horizontal plane. The propulsion assembly 170 also includes an elastic element 174 connected between the traveling device 173 and the push rod 172 and configured to apply an elastic force to the push rod 172, which drives the two push rods 172 to pivot in a direction approaching each other. As shown in FIG. 6, the support frame 130 is also provided with a blocking wheel assembly 175. A blocking rod 176 is provided at the end of the push rod 172. The blocking rod 176 protrudes from the side of the push rod 172 in a direction approaching the conveying device 144, or in other words, in a direction in which the two push rods 172 approach each other. When the traveling device 173 moves backward to a predetermined position, the blocking rod 176 interferes with the blocking wheel assembly 175, causing the two push rods 172 to pivot in a direction away from each other. Thus, when the propulsion assembly 170 retracts to the designated position, the push rods 172 can automatically open to each other, so as not to obstruct the placement of the battery on the conveyor 144. When it is necessary to apply a pushing force to the battery, the push rods 172 can automatically close behind the battery.

The order of steps in the above processes can also be added, combined, or deleted according to actual needs.
